Title: Optical scanner
Inventor: TAKAHASHI HIROSHI
IPC: G02B26/10
Filed: 1990-02-06
Abstract: PURPOSE:To obtain the optical scanner which is small in size, low in cost and high in accuracy by forming a mirror which reflects a laser beam to the end face of the revolving shaft of the mirror by inclining the same at a preset angle with the axial line of the revolving shaft. CONSTITUTION:The laser beam is condensed, reflected and scanned by the mirror 104 which rotates. A photosensitive body 107 is irradiated with this laser beam. The mirror 104 is formed on the end face of the revolving shaft of the mirror with the inclination at the preset angle theta with the axial line l thereof. The laser beam is, therefore, deflected according to the angle theta formed by the incident light and the mirror 104 when the laser beam is made incident on the mirror 104. The irradiation with the laser beam along the prescribed position is thus possible. The optical scanner which is small in size, low in cost and high in accuracy is obtd. in this way.

Title: Noncontact type detector for d.c. high voltage
Inventor: FUJIWARA SADAMU
IPC: G01R19/155
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a noncontact type detector for d.c. high voltages whereby voltages can be easily and safely detected even when a worker's detect position and a power line to be detected are spaced large. SOLUTION: The detector includes a detecting part 3 and an operation rod 4 extending from the detecting part 3. The detecting part 3 has a needle-shaped electrode 5 set to a leading end which is to be directed to a transmission line to generate corona discharge in a space electric field by the transmission line to which a d.c. high voltage is charged. The detecting part detects a discharge current flowing to the needle-shaped electrode 5 because of the corona discharge while the needle-shaped electrode 5 is grounded, thereby reporting that the transmission line is in a charge state. The needle-shaped electrode 5 is comprised of a plurality of needle-shaped wires 11 bundled in a brush. A shielding cylinder 12 for surrounding and shielding the needle-shaped electrode 5 from the space electric field is movably set.  The shielding cylinder 12 is moved thereby changing a relative position to the needle-shaped electrode 5, whereby an operation sensitivity can be adjusted.

Title: Liquid crystal display element
Inventor: HADO HITOSHI
IPC: G02F1/1333
Filed: 1992-02-12
Abstract: PURPOSE:To improve the yield at the time of production by solving the problem of the defect generated by the static electricity electrified during production process. CONSTITUTION:The static electricity is generated in the TFT substrate 6 and counter substrate 8 of the liquid crystal display element 1 by the friction applied thereon during the production process so that the local electrification tends to be generated. The generated static electricity is dispersed by a conductive member 10 and is slowly discharged therefrom and, therefore, the local electrification in the TFT substrate 6 and counter substrate 8 of the liquid crystal display element 1 does not arise. Since the local electrification of the static electricity on the respective substrates of the liquid crystal display element 1 is prevented in such a manner, the defect by the electrostatic destruction occurring in the static electricity is prevented.

Abstract: PURPOSE:To reduce the running cost of the title device by a constitution wherein fins, having moisture adsorbing agent, and a water sprayer are received in an air-tight vessel, while the air-tight vessel is connected to a vacuum source and atmosphere alternately by switching it. CONSTITUTION:First of all, water is sprayed onto moisture adsorbing agent 5 such as silica gel and the like, which is provided on fins 6, to absorb water by the silica gel.
